V SUCTION CLEANING-NOZZLE.

Specification of Letters Patent.

Patented Oct. 12, 1920.

Application filed February 2, 1912. Serial No. 674,973.

To all whom it may concern:

Be it known that I, CHARLES L. Gonorr- NOUR, a citizen of the United States, residing at Canton, in the county of Stark and State ofOhio, have invented certain new and useful Improvements in Suction Cleaning-Nozzles, of which the following is a specification.

The invention relates to an intake nozzle for suction cleaning machines, and the object of the improvement is to provide a nozzle of this character for general purposes, and more particularl for conveniently cleaning carpets or oors in corners or among and around obstacles, as the legs of furniture and the like, and furthermore to provide a nozzle which can be turned or proected in opposite lateral directions from the axis of the tubular handle or stem thereof, by a mere rotation or manipulation of the handle; and furthermore to join the nozzle with thehandle, and the handle with the hose, in such a manner that the handle may be freely rotated to turn the nozzle, and also raised and lowered to enter under overhangin obstacles.

he objects and purposes of the improvement, thus set forth in general terms, are attained by providing a tubular or hollow nozzle having a narrow slot along its under side, with one end closed, combined with a tubular handle connected by a swivel joint with the other end of the nozzle, and also by a swivel joint with the hose, and having an elbow or bend in the handle adjacent to the joint; together with feet on the sides of the nozzle for normally holding the slot downward.

A preferred embodiment of the invention, thus set forth in general terms, is illustrated in the accompanying drawings, forming part hereof, in whiche 1 is a perspective view of the nozzle with the tubular handle and a portion of the suction hose, showing in full lines the nozzle directed to one side of the axis of the handle, and, in broken lines, to the other side thereof;

Fig. 2, a sectional view of the joint and elbow between the handle and the hose;

Fig. 3, a bottom side view of the nozzle showing the elbow of the handle;

Fig. 4, a vertical-longitudinal section of the nozzle on line 4-4, Fig. 3;

Fig. 5, a fragmentary view, partly in sect1on, on line 4-4, Fig. 3, showing the swivel joint between the nozzle and the handle;

ig. 6, a cross section on line 6-6, Figs. 3 and 4;

Fig. 7 a cross section on line 7-7, Figs. 3 and 4:; and Fig. 8, a cross section on line 8-8, Figs. 3 and 4.

Similar numerals refer to similar parts throughout the drawings.

The body of the nozzle 1 is preferably shaped as an elongated hollow cone having one side flattened and provided with a longitudinal slot 2, the side walls 3 of the nozzle being directed downward to form the lips 4 on each side of the slot, which lips are preferably rounded and are located in the same plane to press closely and uniformly upon the floor 0r carpet. The flattened lower side of the nozzle, when formed wide enough, may serve to hold the slot downward so its lips will press uniformly against the carpet or floor.

The smaller end 5 of the nozzle is closed by the wall 6, the lower edgeof which is curved continuously and in the same plane with the lips of the slot, and the larger end 7 of the nozzle is shaped to form the tubular head 8 having the open socket or bearing 9 therein to form a swivel joint with the inserted end 10 of the elbow 11 fixed on one end of the straight tubular handle 12. The axis of this swivel joint is located substantially co-axial with the nozzle, and at an angle with the stem of the handle, and the end of the handle communicates with the cavity of the nozzle.

The feet 13 extending from the sides of the larger end of the nozzle are preferably provided in the plane of the slot; and, as shown, may be formed hollow with a slot in the lowerside in communication with the cavity of the body of the nozzle. Furthermore, the feet may project from the sides of the nozzle and thence extend endwise alongside the swivel-joint with a slight divergence from the middle line thereof, to a point beyond the elbow of the handle, thus increasing the length of the nozzle for cleaning on both sides of the handle. I It will be understood, however, that, whe feet are used, the particular form of the feet illustrated and described. although very desirable. is not essential, the primary purpose of the feet being to normally hold the hps of the nozzle slot flatwise against the carpet or floor when the flattened lower side of the nozzle is not made wide enough for that purose. P On the nozzle end of the straight tubular handle 12 is formed or otherwise fixed the elbow 11 which is preferably curved to an angle somewhat less than ninety degrees, the exact curvature of the elbow not being essential except that, for convenience, it 1s preferably made less than a right angle. The bearing-socket 9 is provided with the mternal annular race-way 15, and the inserted end 10 of the handle elbow 11 is provided with the external annular race-way 16, in which race-ways are provided the walls 17 to form a swivel joint; the balls being preferably entered through an aperture 18 pro vided in the head of the nozzle when the parts are assembled, after which the aperture is closed by a suitable plug .19.

Suitable packing rings 20 and 21, preferably of fibrous material, are wound or placed in the external annular groove 22 and the external annular rabbet 23 provided in the end portion of the elbow, the groove and the rabbet being located .on opposite sides of the race-way, to seal the joint against the admission of air and the exit of dust. The internal annular flange 24: is preferably provided in the socket for the abutment of the rim of the end of the elbow; and these parts are preferably shaped, or beveled as shown, so that the abutment is limited to the peripheral edge of the rim, thus leaving no contiguous faces for catching and grinding dust or grit.

The cross area of the cavity of the nozzle is preferably regularly increased from the smaller toward the larger end and is so proportioned that the cross area at any given point is substantially equal to the opening area of the slot beyond the same point, that is, on the side toward the smaller or closed end of the nozzle; whereby substantially the same degree of suction is insured throughout the length of the slot without leaving any dead or quiescent air cavities in the nozzle for eddying or retarding the dustladen air.

The handle 12 is made straight throughout its length, excepting at the elbow 11 formed or fixed on the nozzle end thereof,-

and is preferably connected with the suction hose 25 by means of the intervening elbow 26, the elbow being connected to the handle by means of the swivel joint 27 coaxial with the straight end of the handle, and the other end being secured to the hose as by means of the tapered socket point 28. The stem of the tubular handle 12 being formed straight from the joint of the hose elbow 26 to the elbow in the handle adjacent to the nozzle joint, it is evident that the handle may be freely rotated upon its axis for properly manipulating the tool without rotating or disturbing the hose or the connecting elbow thereof.

In use of the nozzle, it is evident that it may be turned from one side to the other of the axis of the handle by merely rotating the handle and throwing the free end of the nozzle as illustrated in Fig. 1. And it will be noted that this form of nozzle is especially adapted and useful for cleaning the floor under a series of rows of desks with narrow intervening aisles, as usually arranged in school rooms; for it is evident that the operator standing in the aisle with the handle extending along the same, can

end of the forward foot of the nozzle.

I claim:
